I'm beginning to conclude that refresh pattern in Squid is useless.
I had a neat refresh pattern which is supposed to help cache just
about everything, below:

And it barely cached any of the content it's supposed to. I never once
saw "TCP_HIT" in the logs.
And it seems like when I removed these refresh patterns (leaving the
defaults), I finally saw TCP_HIT's in the log file...
So is refresh pattern useless? Or am I just doing this wrong??!!
I want to be able to cache Windows Updates, Apple Updates and possibly
Linux Repositories as well (without some other fancy program for
that). I also want to be able to cache various Anti-Virus vendors
sites, so updating virus signatures are a lot faster. And to be able
to cache generic content such as images, media files and software.
I want to be able to do this all in Squid... But it seems useless....
Unless someone else has other suggestions? The only thing I'm seeing
TCP_HIT's on is video content, as I'm using VideoCache. But this isn't
enough... I want just about everything to be cached. My proxy server
is a dedicated proxy system with 1 TB of hard drive space for caching.
